Hyperfine structures of La1 are reported using Doppler-free intermodulated fluorescence,Doppler-limited laser induced fluorescence and optogalvanic spectroscopy in a home-made cathode discharge tube.The constants A and B for the levels at 20197.34,21447.86cm^(-1) and constant A for the levels at 19379.40,18156.97,94910.38,and 24409.68cm^(-1) are reported.A homogeneous linewidth less than 40MHz and the different resolutions between fluorescence and optogalvanic spectroscopy were observed.
